HOPPER-CAR.

Patented April 18, 1909.

Serial No. 457,678.

To'all whom "it may concern:

Be it known that I, EDGAR W nnsrnn SUM- MERS, a resident of Plttsburg,1n the county of Allegheny and Stateof Pennsylvania, have invented a newand useful Improvement in similar materials.

ing of the ore and insure discharge of the load,

and closed by a pair oflongitudinally ar- "ranged doors.

- The present invention is an improvement I on the car described in saidapplication, and

the bod has for its objects to improve the sloping end doorrportions soas to prevent the lading from choking and bridging when it slides downto the discharge opening; to improve bolster construction in order toeffective y take care of the stresses and also to permit readyaccesstothe space between said bolsters and the sloping end floors; to providea horizontal web girder secured to the "draft sills for transmittingbuffing and tugging stresses to the car sides, and-used in conjunctionwith an elevated platform so a r'- ranged as to prevent lodgment of oreon said web girder; and other improvements which will be hereinafterdescribed and claimed.

In the, accompanying drawings, Figure 1 is a plan: view ofa portion ofthe carwith parts broken away and the'discharge doors omitted; Fig. 2 isa central vertical longitudinal section through the same; Fig. 3 is anend view of the carj Fig. 4 is a transverse section, the left handportion being taken outside of the bolster and the right hand portionbeing taken centrally through the hopper; Fig. 5 is a verticaltransverse section on the line 55, Fig. 2 and 6 is a deform of top'chordfor the car sides.

tailedtransverse section through a modif ed The caris of the hoppertype, having plate girder side walls extending for the full length ofthe bod and having firmly secured to their ends the Web plate 2 of thebodybolster. These sidewalls are provided atltheir upper edges withasuitable cord 8 and their lower side portions are formed by a separateplate 4 which projects down to the underlrame level and is then turnedinwardly, as at 5, to support the lower edges of the inclined sidehopper sheets 6. Dischargeopenin 7 occupies the s ace transversely ofthe carbetween the opper sheet 6 and is somewhat wider than the track,as shown in Fig. 1', and extends longitudinally of the car for adistance greater than that between the-inner truck wheels. Thisdischarge opening is closed by a pair of longitudinally arranged doors 8hinged at the sides of the car 9, and closing toward the center of thecar, being closed by means of winding chains 10 passing over guidesheaves 11 and onto drums on winding shalt 1-2 mounted transversely ofthe car. The draft sills 13 extend inwardly beyond the'body bolster andat their inner ends are connected by gusset plates 14 to the end 310 ingfloor plates 15.

" be car so far described, excepzfor the shape of the end sloping floorlates, is sub-- stantially the same as that o my application aboveidentified.

The sloping floor plates have their side portions,'as at 16, slopingupwardly, viewed transversely of the car, and secured to the side wallsby means of rivets 17. The portions 16 are on substantially the sameangle as the sloping side hopper plates 6, and extend. inwardly to aline coincident with the side edges of the discharge 0 ening; that is,

side port-ions 16 of the lloor p ates are of substantially the samewidth as the sloping side hopper plates 6. These side portions 16 act asconfining walls for the lading, and the space between the same is ofsubstantially the same cross section from the outeru pper end of the endfloor lates to the discharge opening, so that as tholading slides downthe end floor platesto the discharge opening it does not need to changeits cross sectional area, as is the case where the sloping end floor andsloping side hopper plates meet on a bias or diagonal line, as is thecommon practice. Consequently, the liability of the lading choking andbridging as it reaches the dischz-uge opening is practically overcome,and the free discharge of the load is assured.

A horizontal web girder 20, consisting of one or more plates, is securedto the lower edges. of the end floor plates, as at '21, and at thispoint is also laced atransverse reinforcing plate 22. T 1e horizontalweb girder is secured at its side edges to the plate girder loo sidewalls of the body, and serves to transwit the bufling and'tuggingstresses to said side walls. The outer end of said web girder istapered, as shown in Fig. 1, and has flanged edges at 23.

A t the end of the overhanging portion of I the body is the end plate24, and an elevated platform 25 is also provided in order to permit thetrain men to traverse a loaded train.

Ladders. 26 lead downwardlyfron each side of the elevated platform. iheportion of the horizontal web girder which projects beyond theoverhanging end of the body'is of less width transversely than theelevated platform 25,"as is apparent from big. 1, so that any ore whichis spilled from the shovels in loading the car, can find nolodgment atthe: end of the car except on the elevated latform. The s aces 27underneath the la ders and inclos'ed y the end sill 28 and end side sillmember 29, are open, and the run s of the ladder are small so that theore will'not lodge on the same so that it is necessary to clean off onlythe elevated end platforms. Thismaterially reduces the amount of laborat the mines in cleaning the car before taking ithe same out of the pit.This is of advantage,

as the grade of ore in different arts of the same nnne varies, and asthe olending .gor mixing of the *re 1s started at the mines, the

H operators are careful not to get even small quantities of orefro n onepart of the mine into another, and go to considerable trouble 4 andexpense to clean the cars of all ore lodged upon the same;

This labor is greatly reduced'by thecar described.

,The body bolster compiises side filling or- Web members 30, one on eachside of the draft sill, and a bottom connecting plate or chord 31,together with the web plate 2 rising from the lower port-ion ofthebolster and provided at its upper end with flange riveted to thesloping end ,floor plate The web plate 2 extends continuously from sideto side of the car, and since the space cc-- through thedplate. Thisplate is stifl'ened or strengthene by means of bars, shown as angle bars35, riveted thereto. These stiffening bars pro ect down inside of thedraft SlllS and are riveted thereto, as shown In lr'ig.

'4, and are supported practically on the center bearin pate 36. Theyproject upwardly and diverge outwardly dlagonally in order toeffectively take care of the stresses which come on diagonal lines. Thisoutward divergenceof the stifiening bars also pro the side walls, thusenabling the side Walls to laced onton the lines of the maximum be wiith of the car, so as to increase the cubical capacity ofthe car.

The car illustrated contains numerous other parts, [but as they form nopart of the invention, it is not deemed'necessary to describe the same.
